How HVAC Systems Work

HVAC systems help maintain a high quality of air. That is one basic function. Some systems are more effective than others, and therefore you have a variety to choose from in order to get desired results. These systems work differently in accordance to your climate. Check out the content below to see how different HVAC systems work.

FURNACE

A lot of people think that the furnace is an old piece of technology from the 20^th century. However, this is not the case, as furnaces play a major role in your comfort ability throughout the year. The blower from the furnace helps the air conditioning system in circulating cool air during the warmer seasons. Inside the burner, heat is produced after the combustion of natural gases. Afterwards, the gas produced passes through a heat exchanger. Air from your home’s return air duct is blown over the heat exchanger and then it warms the air. Air is circulated in your house after the furnace’s blower blows the warm air into the duck work. Furnaces usually benefit from air that has been filtered and afforded when the air drawn out of rooms is pulled through an air filter. This is a part of a forced air –split system.

HEAT PUMP OR AIR HANDLER.

If you want to heat and cool your home, you should opt for a heat pump and an air handler. Once they are merged together, they are the best alternative for you. A heat pump transports heat, extracts warm air from your house when its summer season and it reverses this operation during the summer season in order to bring warmth to your home. It might be quite difficult to believe that there is adequate warmth outside to bring warm air during winter to heat up your house. But the truth of the matter is that there is enough heat of about 32 degrees to keep you warm indoors. In addition to that, a supplementary source of heat may be required during the colder climates.

MINI-SPLIT OR DUCTLESS SYSTEM

This is a split system meaning it has components that are located in the interior and exterior of your house. This one unlike the traditional split does not depend on air ducts to supply air in your entire home. A mini-split or ductless system is designed to heat and cool a single room that cannot accommodate or does not have a ductwork. It is powered by electricity and contains a small exterior condensing unit and an indoor that is compacted. And has an evaporator unit, which hangs on the wall. Its function is to direct and control airflow. Mini refers to the interior unit’s diminutive size and inconspicuous appearance. The interior and exterior components are connected using electrical wires and copper refrigerant tubes requiring an opening three inches or lesser in two radiuses. They are the best option for attics and garages that have been turned into living rooms or for additions in houses that would need an extension in their existing ductwork.

THERMOSTAT

A thermostat varies from a very basic and functional system to a sophisticated and rich feature for your house HVAC system. In general, a thermostat controls the operations of the whole HVAC system and it ensures that the temperature is regulated. There are new digital programmable thermostats that are comfortable, efficient and enhance functionality. We can use an example of a programmable thermostat that can be set up to optimally regulate the temperature in your house according to your schedule and your routine in a daily basis. Most of them provide for humidity regulation, ability to change the temperature in various zones in your house and advanced monitoring capabilities. You can also use a remote to control your HVAC system using a wireless device that is a programmable thermostat.

SPLIT AIR CONDITIONING SYSTEM

This system is known as split because its components are located in the indoor and outdoor of your home. Others refer to it as ‘central air’. In the outdoor, you will find it been comprised of a condenser and compressor, while the indoor unit comprises of a fan and an evaporator coil. This is how it works: warm air is removed from your home and is cycled back as cool air through a system of supply and return ducts. It is also powered by electricity. This way, the compressor pumps refrigerant via the system to collect heat and moisture that is in your house. Afterwards, that heat and moisture is removed from the house when warmer air collected from inside is blown over the cooled interior coil, which cools the air. There is heat that is transferred from this process into the coil and is pumped outside, while the cool air is recycled back inside. Split air condition is more effective during the warmer climates. It keeps your house cool and minimizes the levels of humidity.
